Subject: ASoC: sunxi: sun8i-codec: Improve jack button handling and mic
detection
Setup ADC so that it samples with period of 16ms, disable smoothing
and enable MDATA threshold (should be below idle voltage/HMIC_DATA
value). Also enable HMIC_N, which makes sure we get HMIC_N samples
after HMIC_DATA crosses the threshold.
This allows us to perform steady state detection of HMIC_DATA, by
comparing current and previous ADC samples, to detect end of the
transient when the user de-presses the button. Otherwise ADC could
sample anywhere within the transient, and the driver may mis-issue
key-press events for other buttons attached to the resistor ladder.
